Which of the following is the correct compression depth for an infant during CPR?

The correct compression depth for an infant during CPR is 1 1/2 inches. This specific depth is crucial because it allows for effective chest compressions that can adequately circulate blood to vital organs. Infants have a smaller and more compliant chest structure than adults or older children, which necessitates a shallower depth to avoid causing injury while still ensuring that compressions are effective enough to promote blood flow.

When performing CPR on infants, the proper technique involves using two fingers placed on the center of the chest, just below the nipple line. The goal is not only to achieve the right depth but also to allow the chest to fully recoil between compressions, which aids in maintaining circulation. Understanding the nuances of compression depth for different age groups is essential for any lifeguard or rescuer, as it directly impacts the effectiveness of the cardiac arrest response.
